hello, What is the efficacy of food allergen testing? I am following NSD for AS, but I also have Eosinophilic gastritis for which I have to eliminate all diaries/eggs/soya/nuts. This left me quite limited choice. Immunolog wants to test me for Food Allergens but there are many tests and I hear not necessarily reliable. Any advice? I am a little bit stuck here with finding food I am allergic to.
